Norton Attorney-ABSTRACT: A multiple compartmented bottle, formed by a one step bottlemolding operation, wherein a secondary compartment may be contained on aplug securable in the bottle; or by a secondary vessel contained withinthe bottle; and by equivalent methods which will not necessitate a twostep bottle molding operation.

Patented Nov. 3, 1970 1 //Y VE/V 702 $6 504 awe-y -PBNKETMEFTEPFQTHEThis invention relates generally to bottles two or more separatecompartments therewithin.

It is generally well known that it is quite impossible to form internalcompartments in a one step bottle production with the present daymolding technology. Thus the only method heretofore to form internalcompartmented bottles has been to secure a secondary or additionalcompartments to the initial bottle by adhesionthereto. In view of theadvancement of modern technology inother'fields, multiple compartmentedbottles are a necessity, and accordingly, an improved method of theirproduction has been in want.

Accordingly, it is a principal object of the present invention toprovide an improved bottle design which overcomes the above limitation.

Another object is to provide a multiple compartment bottle wherein asecondary compartment is produced within a plug securable to the bottle,so to allow the bottle body to be molded in a one step operation, yetthe final product comprising a multiple compartmented assembly.

Another object is to provide a multiple compartment bottle wherein asecondary compartment is produced by a secondary vessel contained withinthe bottle. 7

Other objects are to provide a multiple compartmented bot tie which issimple in design, inexpensive to manufacture, rugged in construction,easy to use and effieient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein: Y i

FIG. 1 is a side view of one form of the invention, shown partly incross section, I

FIG. 2 is a similar view of a modified form of the invention,

FIGS. 3, 4, and 5 are similar views of yet further modified formsthereof,

FIG. 6 is a cross-sectional view of a modified plug unit showndisassembled,

FIG. 7 is a side cross-sectional view of a bell cap, and

FIG. 8 is a side cross-sectional view of yet another modified form ofthe bottle assembly.

Referring now to the drawing in detail, and more particularly first to FIG. 1, the reference numeral 10 represents a bottle with two or moreseparate compartments according to the present invention, wherein thereis a bottle body 11 including a continuous side wall 12, upwardlyconical bottom wall 13, and externally threaded neck 14 having accessopening 15 therethrough which communicates with interior compartment 16.A secondary opening 17 in the bottom wall 13 may be plugged in variousways. A plug 18 may have a secondary compartment 19 formed'thcrein. Ahead 20 on the plug limits the introduction distance of the plug intothe opening 17.

' part, the wall abutting the flange of the other part. This circularwall would be spaced from the threaded external walls.

In FIG. 5, a modified bottle is shown comprised of parts 51 and 52threadingly secured together; the base part 51 including secondarycompartment 53. The FlG. depicts how the various secondary compartmentsmay be enclosed by a bell shaped cap 54, so as to separate the secondarycompartment from the primary compartment of the bottle. The cap 54includes a stem 55 extending into the bottle neck, and outwardlytherethrough for manual control of the cap.

ln H6. 7, a modified construction shows a bell shaped cap 70 enclosing asecondary compartment unit 71 comprised of compartments 72 and 73, thecap arresting contact of con tents between the two secondarycompartments.

ln FIG. 8, a bottle 80 includes primary bottle 81 with raised concentrichead 82 on inner side of bottom wall 83 so to form a seat for separatebottle comprising a secondary compartment.

A bell cap 85 includes inner and outer lips 86 and 87 enclosingtherebetween the upper edge 88 of the secondary bottle. The bellstem 89abuts at its upper end against primary bottle cap 90; the upper end ofthe stem forming an enlarged head 91 so to allow convenient manual graspthereof. The cap 90 has a conical depression 92 on its underside withinwhich the stem head 91 seats itself.

While various changes may be made in the detail construction, it isunderstood that such changes will be within the spirit and scope of thepresent invention as is defined by the appended claims.

lclaim:

l. A multicompartmented bottle assembly comprising an outer primarycontainer of homogeneous integral construc tion in combination with asmaller open top secondary vessel mounted removably and completelywithin the primary container wherein said primary container has anexternally means for securing the secondary vessel to the primary con-Referring now to FlG,' 2, if plug 21 has a secondary chamber 22 which istoo large to be inserted from the bottom, the plug may be droppedinto-the bottle 23 through the top opening 24. The plug includes athreaded shank 25 extending out of bottle opening 26 for receiving awasher 27 and nut 28, thus securing the plug in fixed position.

' Alternately, the plug could be made, as shown in FIG. 6, with aninternally extending threaded shanlr'ZSa receivable from the outer sidethrough the opening 26 for threadingly engaging a threaded opening 29formed on the secondary comtainer.

2. An assembly as in claim 1 wherein the secondary vessel fits throughthe bottom aperture and is mounted wholly within the primary container.

3. An assembly as in claim 2 wherein the secondary vessel is part of aplug which fits sealingly in the said aperture and includes a head forlimiting the insertion of said plug in the aperture to a predetermineddistance.

4. An assembly as in claim 1 wherein the secondary vessel includes atapered shank adapted to fit abuttingly through said aperture and saidmeans being mounted externally of said container on said shank to forcethe shank into sealing contact with the portion of the containersurrounding the aperture.
